How to cut paper so it can go around a paper cup?

I need to cover a paper cup with pretty paper for a crafts project. But i forgot how you’re supposed to cut the paper so when you put it around the cup it will fit. Please help !

The previous idea would be simplest if you have an extra cup.

If you don’t, then lay the cup down on its side in the middle of a lengthwise sheet of paper, then mark the top and bottom of the cup on the paper. Then *roll* the cup to the right (or left) a little, and mark those upper and lower spots again. Continue doing this till you have an "arc" long enough to fit all the way around your original cup (with a little excess for overlapping)… you can measure the bottom circumference of the cup, or just use trial & error to get the right length.

HTH,
